UK Standard for Heat Interface Units

Established as part of a UK government research project into heat network efficiency, the standard was, and continues to be, developed under the auspices of a steering group of industry experts: 

• Gareth Jones Fair Heat Ltd
• Valeria Khnykina SSE
• Martin Crane Carbon Alternatives 
• Neil Shapland National House-Building Council
• Paul Canning E.ON Energy 
• Phil Jones CIBSE 
• Rufus Ford Department for Business, Energy and Industrial Strategy 
• Steve Harper Galliard Homes 
• Dmitry Mostovoy ENGIE
• Ali Bahar Metropolitan 
• Josu Aurrekoetxea Pinnacle Power
• Robert Hunter L&Q Energy 

PURPOSE

• To enable the performance of different HIUs to be evaluated within the context of typical UK operating conditions thereby enabling heat network developers to evaluate the performance of specific HIUs against design requirements
• To generate operating data on the expected performance of specific HIUs given "normal" operating parameters to enable heat network operators to identify anomalous performance 
• To provide a framework for HIU manufacturers to evaluate the performance of their equipment within the UK context thereby feeding into their continuous improvement development programmes 

OUTPUTS 

• Mapping of key metrics over the duration of each test
• Calculation of the annual Volume Weighted Return Temperature (VWART) from the HIU, with this being a composite of estimations of the annual volume-weighted return temperatures for domestic hot water, space heating and keep-warm functions 
• Evidence of compliance with other performance and reliability metrics, such as speed of temperature stabilisation.
